Hello. I want to use this NIC but I'm unsure if it's supported. If yes, is it built-in or via 3rd-party KEXT? thanks

Note that Intel has many different NICs labeled as "Pro 1000", with different drivers (although generally the newest drivers support all models, and older drivers don't support Pro 1000 NICs released after the driver's build date). The dual port and quad port cards use different chips.

The product code (e.g. EXPI9404OT) is the best way to identify the cards (Pro/1000 PT is ambiguous, and refers to multiple cards with different chipsets and drivers).
